Plain English summary of protocol

Background and study aims
Young basketball players often take part in regular high-intensity training during a period when their bones and muscles are still developing. Good nutrition may help support bone health, muscle function and recovery during this important stage of growth. This study aims to find out whether a daily protein-mineral nutritional supplement can improve markers of bone health and muscle function in adolescent basketball players.

Who can participate?
Adolescent basketball players aged 14 to 18 years who have received systematic basketball training for at least 3 years and currently train for at least 15 hours per week may participate. Participants must be in good general health, able to complete the study tests and have written consent from both themselves and their legal guardians.

What does the study involve?
Participants are randomly assigned to one of two groups. One group receives a daily protein-mineral nutritional supplement for 16 weeks. The other group receives a placebo drink that looks and tastes the same but does not contain the active nutritional ingredients. Neither the participants nor the researchers know which group each participant is in until the study is completed. Blood tests, bone assessments, muscle strength tests and performance tests are carried out to compare changes between the two groups.

What are the possible benefits and risks of participating?
Participants may benefit from closer monitoring of their bone health, muscle function and training-related health indicators. The nutritional supplement may help support musculoskeletal health, although this cannot be guaranteed. Possible risks include mild gastrointestinal discomfort, such as bloating, nausea or diarrhoea. Blood sampling may cause temporary discomfort, bruising or light-headedness. Safety indicators are monitored throughout the study.

PurposeTreatment
Scientific titleEffects of a 16-week multi-component protein-mineral supplement on bone turnover and muscle function in adolescent basketball players: a randomized double-blind placebo-controlled trial
Study objectives The primary objective of this study is to evaluate the effect of a 16-week multi-component protein-mineral nutritional supplement on bone turnover in adolescent basketball players undergoing high-intensity training.

Secondary objectives are to assess changes in bone microstructure, bone mineral density, muscle strength, functional performance, and safety/tolerability. Exploratory objectives are to investigate potential muscle-bone adaptive responses, including changes in myokines, osteokines, and related regulatory biomarkers.
Ethics approval(s)

Approved 01/08/2024, Research Ethics Committee of Chizhou University (No. 199, Muzhilu Road, Guichi District, Chizhou, 247200, China; +82 (0)5662748827; czxyjy@czu.edu.cn), ref: CZ20240801

Health condition(s) or problem(s) studiedBone metabolic stress, suboptimal musculoskeletal adaptation, and muscle function changes associated with high-intensity training in adolescent basketball players
InterventionEligible participants are randomly assigned in a 1:1 ratio to either the intervention group or the placebo group. The randomisation sequence is generated by an independent statistician using a computer-generated random number table. Block randomisation with a block size of 4 is used, stratified by sex and age group, namely 14–16 years and 17–18 years. Allocation is implemented using sealed, opaque, sequentially numbered envelopes.

Participants in the intervention group receive a daily multi-component protein-mineral nutritional supplement for 16 weeks. Each serving contains 28 g of protein, including whey protein and collagen protein, combined with calcium, phosphorus, magnesium, vitamin D3, vitamin K2, lactoferrin and casein phosphopeptides. The supplement is taken within 30 minutes after training or after breakfast on non-training days.

Participants in the placebo group receive an isocaloric maltodextrin placebo for 16 weeks. The placebo has an identical appearance, taste and packaging to the intervention product.
Intervention typeSupplement
Primary outcome measure(s)
  1. Serum procollagen type I N-terminal propeptide (P1NP) concentration measured using an electrochemiluminescence immunoassay from fasting morning blood sample at baseline and week 16. The primary endpoint is the change in serum P1NP concentration from baseline to week 16.
Key secondary outcome measure(s)

1. Serum C-terminal telopeptide of type I collagen concentration (CTX-1) measured from fasting morning blood samples using a validated laboratory immunoassay at baseline and week 16.
2. Serum bone-specific alkaline phosphatase concentration (BALP) measured from fasting morning blood samples using a validated laboratory assay at baseline and week 16.
3. The P1NP/CTX-1 ratio is calculated from serum P1NP and CTX-1 values at baseline and week 16.
4. Bone mineral density is measured using dual-energy X-ray absorptiometry (DXA) at baseline and week 16.
5. Bone microstructure is measured using high-resolution peripheral quantitative computed tomography (HR-pQCT) at baseline and week 16. Parameters include trabecular bone volume fraction, trabecular thickness, trabecular number, cortical thickness, cortical bone mineral density, estimated stiffness and estimated failure load.
6. Knee extensor muscle strength is measured using isokinetic dynamometry with the Biodex system at baseline and week 16.
7. Functional performance is measured using vertical jump height and 20-metre sprint time at baseline and week 16.
8. Muscle-bone adaptation biomarkers, including myostatin, irisin, insulin-like growth factor-1, undercarboxylated osteocalcin and fibroblast growth factor-23, are measured from fasting blood samples using validated laboratory assays at baseline and week 16.
9. Safety and tolerability are assessed using adverse event records, gastrointestinal symptom scores, liver function tests, kidney function tests, serum calcium and urinary calcium/creatinine ratio during the intervention period, including baseline, weeks 4, 8, 12 and 16, and the week 20 follow-up assessment.
